Thank you, I agree Tint, CRI, and Color Temperature are all independent variables.
Also agree that Low CRI LEDs have Negative R9, which may help explain why they make red things look brown, and the palm of my hand look lifeless.
Specific to the High CRI charts I posted, it is coincidentally also true that the lights with the lowest R9 happen to also have the Greenest tint (above the BBL), and the lights with the highest R9 happen to also have the most Rosy tint (below the BBL).
Here is a Low CRI light, courtesy of maukka, with Negative R9, that happens NOT to have Green tint, in fact it lands perfectly on the BBL.
But this is a Low CRI LED, that makes Red things look Brown, and I did not make this thread to talk about them. The point of this thread was specifically to compare the R9 values of some common and popular High CRI LEDs.
I did not expect to discover that the High CRI LEDs Zebralight uses happen to have some of the lowest R9 of the group, but of course Zebras are focused on Brightness, not CRI. Most of the flashlight market is brightness driven, and Low CRI is common in the majority of offerings. So is Green tint. It seems to me that the N219b is one of the few offerings that tends to avoid Green tint, but not always.
Im such a snob about tint, that I find N219b is a personal favorite, particularly the 9080 versions.
thanks for adding to my knowledge. Will SBT70 work in an S Mini (w XM-L2 Tir)?
And can you share a link to where you found those charts please?
Here is another group of R9 comparisons, for some of the 219c 2700k, 3000k, 3500k, qnd 4000k offerings from Clemence
These all happen to have more yellow/green tint than the N219b I posted earlier, and coincidentally the 219c also have R9 bars that are shorter than the two 219b in the first post.
